After a decade-long decline in U.S. military shipbuilding budgets, from $11.5 billion in 1991 outlays to $6.7 billion in 2000, spending on ship construction is back to the $10 billion level. The Navy is building new generations of submarines, supply ships and expeditionary warfare vessels. The venerable Nimitz-class aircraft carriers and Arleigh Burke destroyers are still in production. Furthermore, new destroyer, aircraft carrier and littoral vessel designs are in development, moving quickly toward metal. Today, at some shipyards, the challenge is not finding more work but finding enough workers.
